Abstract

A new lignan, smallanlignan B (1) together with seven known lignans (2-8) were isolated from the leaves of S. sonchifolius. Their structures were elucidated by the analysis of spectroscopic data. The antioxidant activity of smallanlignan B was also evaluated and it showed antioxidant activity with an IC50 value of 2.18 mg/mL.
